Y = x - 6
x = -4
plug in the second equation in to the first
y = -4 - 6
y = -1(4 + 6)
y = -1(10)
y = -10
The solution to the system is not listed in the options. The correct solution is (-4, -10).
The solution is the thing they always have in common.
2x-8=x+4
Get the x to the other side and the 8 to the opposite
2x-x=4+8
X=12
Answer:
Part A:
Blueprint 10 inches ⇒ Actual 35 feet
Blueprint 20 inches ⇒ Actual 70 feet
Part B:
The cost of the cover is $857.5
Step-by-step explanation:
Part A:
∵ The drawing scale is 2 inches for 7 feet
∵ The length = 20 inches and the width = 10 inches
∴ The actual length = (20 × 7) ÷ 2 = 70 feet
∴ The actual width = (10 × 7) ÷ 2 = 35 feet
Part B:
∵ The cost per square foot = $0.35
∵ The area of the pool = 70 × 35 = 2450 feet ²
∴ The cost of the cover = 2450 × 0.35 = $857.5
46/287.5 = .16
.16x287.5 = 46
The answer is 16%
